For example some people have singing capacitors under Linux but not Windows because of the higher timer IRQ frequency of Linux combined with poorly shielded motherboard components.

Am Samstag 14 Oktober 2006 05:09 schrieb Lee Revell: I'm not really a home theater expert, but the DVD standard is AC3 which is also known as DD. DVD standard limits bitrate to 448kbits, though ac3 allows up to 640kbit. DTS is an older, less common format. Nope, it's actually newer, but an optional format. I *think* that if AC3 passthrough works then DTS must work - it's just a matter of setting a non-audio bit on the stream. Depends on the receiver. Some play the stream even if non-audio is not set. It could be that non-audio is not set, but receiver detects DTS but not DD if the non-audio bit isn't set. There exist DTS-Audio CDs, which means instead of PCM DTS streams are recorded as CDDA tracks. So here the receiver can't rely on the non-audio bit.

Sorry, I must respecfully disagree. I've just tried this command:

[Alsa-user] Surround sound via optical spdif out
Hi, I am running a mythtv box based on Mandriva 2007 on a AMD 3200xp (Dual core) on an AM2 chipset. I am attempting to get surround sound audio out to my stereo via an optical s/pidf cable. With some help from kirberich crimsum I adjusted the model= line in my modprobe.conf and applied the patch from http://hg-mirror.alsa-project.org/alsa-kernel?cmd=changeset;node=e51177a60747522a60bc1599aa5b2db22d4770a4;style=gitweb Unfortunately, I still am unable to get surround sound to work. The way we were testing this is with speaker-test -Dplug:iec958 -c6 (note: iec958 and spdif are the same for this motherboard). I am getting sound from my left and right speakers, but nothing from anything else. So any more troubleshooting help would be greatly appreciated.

just to chime in ... I have a similar pioneer
look on your display, where the little digital / analog display box
is. when receiving a encoded pcm bitstream, the display will show:
DOLBY
DIGITAL
or
DIGITAL
DTS
depending on the encoding used... when a normal non-encoded pcm is
received the indicator will just read DIGITAL

Is AC3 the DVD standard (I didn't think so...)? I'm not really a home theater expert, but the DVD standard is AC3 which is also known as DD. DTS is an older, less common format. So you should be able to play DVDs in surround. I'm not sure why the other file didn't work. It looks like mplayer tried and failed to guess the file type? I *think* that if AC3 passthrough works then DTS must work - it's just a matter of setting a non-audio bit on the stream. Lee - Using Tomcat but need to do more?
